Strong pre-release tracking, effective horror marketing from Blumhouse and Universal, and ongoing genre momentum in 2026 drove trader consensus toward the 27-30 million range for "Other Mommy." The Jessica Chastain-led supernatural thriller benefited from solid trailer buzz and a wide 3,365-theater release timed near Halloween, helping it exceed initial projections despite dismal reviews and a D+ CinemaScore. Comparable recent Blumhouse titles and the film's modest $18-19 million budget further supported expectations of a mid-range opening. An upset below 24 million or above 33 million would have required either a sharper word-of-mouth collapse or unexpectedly robust family and repeat viewings that failed to materialize in final estimates.
